"To all whom it mag concern: Be it known that I, SAM EL, L. B NNETT, a'citizen of the United States residing at Bellows Falls, county of Windham,-rS tate-' of Vermont, have invented an Improvement in Throttle-Locks for Automobiles, of which the following description, in connection with likeJcharacters on the drawing representing likeparts. w t A This inventionfhas for 1ts object gto pro-' vide a novel throttlelever and quadranti member which may be attached totheordinary quadrant arm of an automoblle'and by which the throttle lever can'be locked 1n closed position and may be held ln any ad justed position. I i 1 f It is oftentimes very dQSlIttblQ to beable anylocks'for this purpose; v ,Myinvention aims to provide a novel but most automobiles are'not provided with applied to the quadrant arm of" any" auto-. mobile and by which the throttle lever may be locked. V 1 j' V My improved 'quadrantmember can be provided with notches of any degree offine: ness' so that in casethe notches of'thecquad rant arm-are too coarse for a fine 'regulation oi the speed of the" automobile such, fine regulation can be secured by usingmy. improved auxiliary quadrant member. j I will first describe a selectd mbodiment ofmy invention from which the principle thereof will be readily Japparentand'wfll thenpoint out the novel features in the ap pended claims. v In the drawings'wherein I have illustrated one embodiment of my invention, Figure 1 is a perspectiveview of anautomobile steering wheel,the.stem therefor and the throttle lever showing my improvements. applied thereto; Fig. 2 is an enlarged plan viewof the detachable segment and throttle lever, said figure being taken on the section bb, Fig. 3; Fig. .3'is a side view off the detachable seglnent 'and the throttle lever I lock;

This segs mentor quadrant is showniasja quadrant armfi having {notches 7 formedfithe rein and.

carriedby a quadrant; member 5 which is v permanently secured to the head .26 v of the The parts thus far; described, are such as are commonly found; in automobiles and form no part of my present invention Y :throttle lock [is-i designed to be detachably applied tothequadrant arm 6. This combined, auxiliary. quadrant. and lock or detachable member, as it maybe-called, is

designated by. 8 and it is" formed with the herizontally-extendini portion 10-which extends across the' notc ed face of the quadrant arm 6 ,and Y with-the downwardlyrex tending flange,9 which overlies the-outs? face of thequadrant arm 6. The horizont portion 10 of the detachable quadrant mem ber is preferably'providedwith a groove "11 to .receive the upper edge of the quadrant ,arm 6, and'said portion 10 is provided-on its upper face with notches .12 "tocooperate v with lithe throttle-lever 3. The notches 12 may be made asfine' or coarse'as desired but preferably they will be made comparatively fine. ,In many automobiles the notches'7 with which the'quadrant' arm is provided are comparatively coarse, so coarse, in factyas to prohibit a, fine regulation of the speed'of the automobile. By making 'thenotchcs 12 on my detachable quadrant; member comparatively fine a very fine adjustment of-3 the speed of theaut'omobile'can be'secured'.

The detachable quadrant member may lie secured to the quadrant arm' inf any "suitable way which will permit it to be'readily placed in position thereon or removed therefrofnQ q One i simple construction is "that shown Figs. 2, 3 Iand 5 wherein i the detachable which extendsthroughthe flange}? and-the} quadrant arm and has alnut 14 appliedthere-.j 0

turning-thereby so that the screw 13 can be tightened or loosened by turning it with a screwdriver. This detachable quadrant 1 My improved auxiliary quadrant and 70 fee will, of course, have the same curvature as the quadrantarm and will merely fit over the latter, but since it is' provided with relatively. fine notches it is-possible,to-secure a correspondingly fine adjustment of the throttle lever r qu'adrant'fi 1s shown as pro- The mam vided' at its endwith a projection 14." I have also' provided the auxiliary quadrant .member 8 with'a projection at its end and with ahotch 160. to receive the projection"14',;as shown in Fig. 6.

: lhedetachable quadrant member herein shown is provided with means for locking t of l a locking lever-in the shape of a'loclcing the throttle lever in its closed position thereby preventing any unauthorized person from tam eri'ng with the throttle. This-locking of the throttleis accomplished by means finger 16 pivotally mounted on a stud or screw 17 .carried by the detachable quadrant. This finger 16 canswin from its operative ositionshown in' ful .lines Fig. 3

into. its' noperative position shown in dotted lines-Fig. 3. Whenit is in its operative p6 sit'ion it-locks the throttle lever in its closed position'and' thus prevents the throttle from being opened, while when it is inits dottedline position tit is out of'the path of movement of the t some leverandthe latter can.

be} operated .as usual. The flange 9 is shown as beingprovidedwith ja depending car 18 having one or more apertures 19 formed. therein' -andlthe lockin finger-- 16 has. an

dies t e-ear 18'and extension 20, which over whichiis provided with two; apertures 21 and 22, Whenthe finger is-in its ,operatlve position', shown in full lines Fig. 2 the aper-' ture 21 is-,inf alinement with the aperture 19 the positionwhich the throttle lever oc'-- and the locking finger can be locked in this Qperative position by means ,of' a padlock 23 .or any other suitable locking device wh ch is adaptedtojbe inserted through the alined r apertures 19 and 21. On the other hand,

whenthe locking member is in its inoperative position then the aperture 22 comes into alinement with the aperture 19 and the same locking device 23 can beusedto lock the 1 I locking lever in 'itsinoperative position.

. I may if; desired provide the extension 20 with one or more other apertures 24:. Thepurpose of this construction is to provide] for lockingthe throttle closed regardless of cupies atlsuch time. In some constructions the throttle might be closed when the lever B. is in the dotted lineposition Fig. 3, while in other'cases the lever would be 1n the full line position fwhen the throttle is closed.

\ When the automobile is running the looking finger will be locked in its inoperative position. Ifthe operator desires to leave the automobile at some place for a greater or less lengthof time, he will closethe throttle and then swingthe locking finger into 4 means associated with said auxiliar its operative osition andloclr the finger in this position y the locking device 23. The

throttle-cannot be opened except byv unlocking the locking finger and this can be done only by the roperly-authorized person. My invention, t erefore, provldes not only. a means for-providin a fine adjustment of? the throttle which is very desirable espe cially in a crowded city, but it also ro- Vides against thetheft-of the automobil e.

My improvement can be applied to any automobile and it is very inexpensive to manufacture.

I have herein shown the clamping-screwv 13 by which the auxiliary quadrant member is held to the quadrant arm as being situated behind the extension 20 of the locln'ng finger so that said extension prevents the clamping screw from working loose or being ,removed. This clamping screw 13 mayfibe n ger downward or-inja position bottom side removed only by turning the locking up from that shown'in Fig. 3.

Having fully described my invention, what I claim as new-and desire to secure by Letters Patent is I 1 .'As anarticleiof manufacture, an aux iliary quadrant member presentm a curved body portion havingon' its un er side a quadrant-receiving ooveandon its upper side a series of notch es to engage the throttle lever, and a projection, constituting a lever stop, and clampingmeans associated with the body and ada ted to-clamp said auxiliary quadrant mem er. to the quadrant armof an automobile.
